Sargent panel

On holiday at the moment in the new forest, my panel is working fine but its making a crackling noise now and then but seems to be more frequently at night when we are trying to sleep. Any ideas what it could be and what I can do .many thanks Paul.

I would suspect that it may be related to the problem that you had earlier this year with the mains socket(s). If the wiring has been sufficiently disturbed (at some point in the past) to pull the mains wiring out of the back of the main unit, I would check the wiring on the back of the control panel to make sure none of the connections there are loose.

The wiring plug was tight at the back of the panel but pull it out and left for 2 minutes then put it back and all is well at the moment.  Might get some sleep tonight. Thanks moJo.
